5.4 Temperature calibration
1. The temperature of the instrument had been
calibrated before delivery, but due to some other
factors the temperature may vary from the actual
temperature and the deviation can be corrected by
temperature calibration.
2.In order to ensure the temperature control
accuracy, based on the temperature calibration
function, it is recommended to calibrate the
temperature whenever the heating block is changed.
The device adopts the three-point temperature
calibration method, HC110-Pro, HCM100-Pro
calibration temperature is 10℃, 50℃ and 90℃，
H100-Pro,HM100-Pro calibration temperature is
37℃，60℃ and 90℃.
The linear calibration of the three temperature
points ensures that the accuracy of the three
temperature points of the system within ±0.5℃.
At the time of temperature calibration, the ambient
temperature must be 15 to 25℃.
Caution：
The temperature of device has been calibrated
before delivery, so please don’t use this
function at will.
Calibration procedure:
Inject silicon oil into the hole in the center of the
heating block. Place the thermometer probe in the
oil filled hole.
1. Switch power ON the instrument，Press both the
Prog and Temp buttons at the same time to enter
into calibration mode while self-checking only.
(Please note that the instrument cannot enter into
calibration mode if the self-check is complete.)
